“…As for the six degrees of freedom motion of ROV, which include go forward, go back, go up, go down, and stay, it should be operated by the control unit. And these commonds can be achieved by just using a game controller with elaborate design [10]. When focusing on the maintenance for a small crack or defect that requires more precise operation, operation buttons may be adopted.…”

Since many dams and bridges constructed in last century are facing serious safety issue resulting from leakage, erosion, and crack, it is increasingly urgent to develop more inspection and repair technologies that can be used for the maintenance operation. This essay introduces the practical application of underwater structure inspection conducted by remote-operated underwater vehicle. The applications include Mullaperiyar dam, Amagase dam, Aqua bridege, and Shorenji dam. And the application skills are summarized in inspecting small leaks of dam in clean water, inspection in turbid water, conducting survey in easy-entangled environment, and operation in flowing water. The advantages of remote-operated underwater vehicle compared with traditional divers are accumulated, and the remaining problem of existing remote-operated underwater vehicle are also summarized. This paper further provides experience of its operation in low-visibility water and stabilizing its position in turbulence, as well as solving the difficulties of getting the cables entangled in easy-winding water. Besides, an outlook is provided for remote-operated underwater vehicle’s development tendency in the field of underwater detection and reinforcement, with the purpose of addressing more critical problem in maintaining underwater structure in the future.

“…The accuracy of the empirical formula estimation method is relatively lower than the latter two and is mostly used for inertial hydrodynamic coefficient calculations and hydrodynamic coefficient calculations that do not significantly affect the model calculation results of the second order and above. The accuracy of the hydrodynamic coefficient obtained by the ship model test method is the highest among these three methods, but the cost and requirements of the test equipment are high [6,7]. The method of simulating ship model tests using CFD technology has advantages such as being unaffected by the accuracy of the test equipment and low cost, and can provide an ideal simulation environment that is not disturbed by the external environment, so it is widely used to calculate the hydrodynamic coefficients of underwater vehicles [8].…”

Remote Operated Vehicle (ROV) can replace humans in inspecting and maintaining water facilities such as reservoirs and dams. Connected to surface support equipment through umbilical cables, the umbilical cable allows the operator to control the ROV's operations remotely from a mother ship or shore. Using the ROV as an underwater operational platform, precise and efficient underwater inspection and repair operations for hydraulic structures can be achieved by mounting underwater mechanical arms, pan-tilt cameras, cleaning and cutting devices, etc. This paper designs an observation-class ROV, carries out structural design of the ROV body, selects and models sensors and actuators according to actual needs, and provides a method for using the FLUENT software to perform hydrodynamic calculations and obtain hydrodynamic coefficients based on the model.
